Really confused

I took a pregnancy test 5 days ago and another one maybe 2 days ago both came back negative at that point I hadn’t missed a period yet but had a lot of pregnancy symptoms which I’m still having.I am now only 1 day late but I feel like if I was pregnant I would’ve gotten a positive by now? Or can I be wrong ?

I’ve recently had a baby (2 months ago) I wouldn’t mind having another Ive always wanted children close to age so am I possibly pregnant again and should wait to take another test or are my cycles just a little off right now from previous pregnancy?

P.s. for someone who asked : Yes,I did have my postpartum period I was actually very shocked at how quickly I got one many ladies have told me it takes weeks even months to get a period after ,Which is why I am more confused on this
